Made very well, fantastic tool.
This is a simple inexpensive tool.............that is worth its weight in gold. It makes torqueing a carbine receiver extension extremely easy.
This is a well made tool that is reasonably priced.
With this block in a solidly mounted vise, torquing the castle nut to 40 lb-ft of torque is no longer an episode of the Keystone Cops. It is now an easy, quick, single-person job. We have all been there, myself included. A mixture of vise pads to protect the tube/receiver and a helper (or two) to coordinate the job. This block makes the crazy stuff we did in the past a smooth and satisfying task. Block is solid. Two nylon thumbscrews deter the buffer tube from sliding in the block. I am very satisfied with this purchase. Wish I had it during my first build.
Great product! An absolute must for your AR build.
I was looking for a receiver block to hold the buffer tube during installation and the only other one was always out of stock and way too expensive. Then I found this one and it is perfect for the application. cost is great and it works like a charm. It is well worth the cost for the convenience of helping with assembly. I'm sure I haven't discovered all the benefits yet but I'm sure it will become a highly used tool.
I find this product to be great!!! It’s just what I needed for my project, and I highly recommend this to everyone!!!!! Thank you again Botach!!!!!!
If your thinking about building your own at-15, do not pass this up, not all buffer tubes come with an anti rotation cut for the buffer detent no matter how cheap or expensive so if you don’t want to risk the tube rotating and the end plate messing up the threads when torquing 40 foot pounds please buy this, you will not regret it, screws are polymer and will not scratch your tube, just slide in easy and steady, also make sure you clamp down pretty good with your vise to avoid this tool from moving.
